Why does my Macro Error In Shared Workbook

[RNB]

I created the Macro when it was not a shared Workbook and everything works
great. When I turn on the share workbook it errors out when it starts to read
the Module. Why would this happen and how do I fix it.

Search on Shared Workbooks in help and select the topic FEATURES THAT ARE
UNAVAILABLE IN SHARED WORKBOOKS from the topics returned:

The list details what cannot be done in a shared workbook, and if your macro
is attempting to use one of the unavailable features it will fail.
